Hi, i'm a dovecot-newbie and also new at this mailinglist. I'm try to configure an mailserver with dovecot2, postfix and postfixadmin. At this time i struggle with acl and shared namespace.

My goal is, that every user get an archive-area on an separate storage without quota (quota isn't running yet). With: namespace { type = private separator = / prefix = "archiv/%u/" location = maildir:/var/data/archiv/%d/%n:INDEX=/var/data/indexes/archiv/%u:LAYOUT=fs inbox = no subscriptions = yes list = yes }

I see the folder, but i can't subscribe them (with thunderbird, or roundcube). With roundcube i can add a new folder below - so i use the trick autocreate5 = archiv/%u/archiv autosubscribe5 = archiv/%u/archiv

This is as workaround ok - or is this a "must be"?.

But the user should also be able to share parts of the archiv-mailbox with other users (partly on different domains). If i change the type of namespace to shared, i can't access the archiv-folder.

The logfile shows problems with the acl (but also with private namespace): Jun 30 11:15:11 imap(test@example.com): Debug: Namespace : type=shared, prefix=archiv/test@example.com/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/data/archiv/example.com/test:INDEX=/var/data/indexes/archiv/test@example.com:LAYOUT=fs Jun 30 11:15:11 imap(test@example.com): Debug: fs: root=/var/data/archiv/example.com/test, index=/var/data/indexes/archiv/test@example.com, control=, inbox= Jun 30 11:15:11 imap(test@example.com): Debug: acl: initializing backend with data: vfile Jun 30 11:15:11 imap(test@example.com): Debug: acl: acl username = test@example.com Jun 30 11:15:11 imap(test@example.com): Debug: acl: owner = 0 Jun 30 11:15:11 imap(test@example.com): Debug: acl vfile: Global ACL directory: (none) Jun 30 11:15:11 imap(test@example.com): Debug: Namespace : Using permissions from /var/data/mail/example.com/test: mode=0700 gid=-1 Jun 30 11:15:11 imap(test@example.com): Debug: acl vfile: file /var/data/archiv/example.com/test/dovecot-acl not found Jun 30 11:15:11 imap(test@example.com): Debug: autocreate: Failed to create mailbox archiv: Permission denied Jun 30 11:15:11 imap(test@example.com): Debug: Namespace archiv/test@example.com/: Using permissions from /var/data/archiv/example.com/test: mode=0700 gid=-1 Jun 30 11:15:11 imap(test@example.com): Debug: acl vfile: file /var/data/mail/example.com/test/dovecot-acl not found

I'm wondering about "...dovecot-acl not found" because dovecot create an file "dovecot-acl-list" :

ls -l /var/data/archiv/example.com/test/

drwx------ 5 dovecot dovecot 4096 30. Jun 10:30 archiv -rw------- 1 dovecot dovecot 0 30. Jun 10:30 dovecot-acl-list

Must the acl first initialized? My first try fails also: doveadm acl set -u test@example.com archiv/test@example.com/archiv test@example.com lrw doveadm(test@example.com): Fatal: Invalid ID: test@example.com

Not clear for me, what kind of id doveadm needs...

I use 2.0.13 for testing. I put my config at the end of the mail.

I'm happy if someone can hit me in the right direction, where i make the mistake.

Best regards

Udo
